Printing Suggestions for Typed Files

I recommend two-page-to-a-side and/or double-sided printing to save paper. Color printing is nice, but B&W printing is cheaper.

These are pdf files. You can get the free Adobe Reader at http://www.adobe.com. Get a version that is compatible with your system!

Class Notes

Many students benefit from printing the notes for a lecture beforehand, reviewing them, and commenting on them in class.

You may want to take personalized sketch notes in class.

Corrections: (0:48-1:07) The double-nappe cone (or simply cone here should not be thought of as finite, so there are no bases nd there is no base perimeter. The term directrix is used elsewhere, especially when describing parabolas.

In previous semesters, the final was cumulative. For your information, here was the outline provided: Math141OldFinalOutline.pdf
